SPECIFICATION forming part of Letters Patent No. 442,201, dated December9, 1890.

Application filed January 27, 1890. $erial No. 838,235. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE ll. POUNDER, of Fort Atkinson, in the countyof Jefferson and State of lVisconsin, have invented new and usefulImprovements in Butter-\Vorkers; and I do hereby declare the followingto be a full, clear, and exact description of said invention, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

In the drawings, Figure 1 is a top plan view of my complete device. Fig.2 is a side elevation of the same device, parts being broken away toshow the construction more fully. Fig. 3 is an end view of the frame.Fig. i is a central vertical section of a central portion of therotating table and devices connected therewith. Fig. 5 is a sideelevation in detail of the device for raising and lowering thecorrugated rollers. Fig. 6 is a modified form of the same portion of thedevice shown in Fig. i.

A is the frame supporting the operative parts of the butter-worker. Acircular table B, which is depressed or dished centrally, is supportedand rotates horizontally on bearing-wheels O C, journaled in blocks onthe frame. These wheels C G bear against a circular track 1), secured tothe under side of the table 15, the periphery of which track 1) forms acrown toothed wheel or rack E, which meshes with the toothed wheel F onshaft G, by the rotation of which the table is revolved. The shaft Ghasits bearings in the frame, and is provided with a beveled pinion G,which meshes with a beveled pinion on the driving-shaft ll, which isprovided with fast and loose pulleys I and I, for carrying thepower-transmittin g belt.

The top surface of the table ll inclines downwardly inwardly from theperiphery toward the center, and at the center the table is providedwith a shallow cup-like depression K, from thebottom of which at thecenter of the table a vertically down wardly-leading d not L isprovidethth ro ugh which buttermilk is discharged from the surface ofthe table. This d not L is preferably constructed in or lined by awoodentube M, which is surrounded and reenforced by a metal bushing N, and theduct is continued downwardly through the frame A in the manner shown inFig. 6, or in an equivalent manner, as shown in Fig. 4.

Above the table B and at one side thereof are two frusto-conicalcorrugated rollers O O, which are located at a distance from each otherand at a little distance above, but so that their under surfaces,respectively, are parallel with the adjacent surface of the table 15.These rollers extend from the periphery of the table 13 to or near tothe edge of the depression K. These rollers O O are each fixed on aspindle O, which has its bearings in an independent frame P, supportedadj ustably on the frame A, entirely at one side of the table B. Theframes P P are each provided with a face which his against an uprightpart of the frame A, and is secured thereto adjustably vertically bymeans of a bolt R, inserted in the frame A and passing through a slot Stherefor in the frame P. The frame P alongside the slot S is providedwith a toothed rack T, and a block T on the bolt R, underneath the nut Rthereon, is provided with corresponding teeth which engage the rack T,whereby the frame P may be socurely held on the frame A at the point towhich it is adjusted vertically. The spindles 0' O are each providedwith a fixed cogwheel U, which mesh with the cog-wheel U, fast 011 thedriving-shaft ll. The faces of the teeth on the cog-wheels U U areslightly curved laterally to provide for gearing properly with the wheelU while located at an angle thereto.

The end legs V V of the frame A are secured rigidly together and aresecured rigidly to the head-block XV, which head-block is pivoted to theframe A by means ofthe bolt and is further secured to the frame by thebolt \V. These legs when thus secured to the frame A by the bolts V andV, are rigid thereon in an upright position, but the bolt \V beingremoved, the legs are then secured to the frame A only by the pivotalbolt V, on which they may be swung underneath the horizontal portion ofthe frame in the manner indicated in dotted lines in Fig. 2, whereby theframe is put in convenient condition for moving it about, or, whendesired, for packing it for transportation.

It will be understood that by reason of the construction hereinbeforedescribed the frusto-conical rollers O 0 have no direct connection withthe table B, nor is there any part of the frame that supports therollers that passes through the table; but in some cases where greatstrain is put on the machine by heavy Work it is better to connect theframes P P at their rear ends by a removable extension-rod y. This rod yis Very conveniently formed in two parts, the outer ends of the rodsbeing turned by screw-thread into the frames P P, the inner adjoiningends of the two parts being connected together by acoupling-nut havingright and left handed screwthreads for receiving the ends of the twoparts of the rod therein, the nut being thus adapted for drawing the twoparts together or forcing them apart, as desired.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a butter-worker having a horizontally-revolving table, thecombination,with two frusto-conical rollers fixed on revolving spindlesdiverging outwardly above and at one side of the table, and independentverticallyadjustable framesin which the spindles have elongatedbearings, the spindles being provided with cog-wheels which mesh at anobtuse angle with an interposed cog-wheel on a driving-shaft, of anextension-rod connecting the outer ends of the spindle-supportingframes, said rod being formed in two parts, joined by an adjustingcoupling-nut having right and left hand screw-threads, substan- 3 tiallyas described.

2. In a butter-Worker having a revolving table and frusto-conicalrollers located and rotating parallel with and at an adjustable idistance above the table, the combination, with the frame of themachine, of spindlesupporting frames in which the spindles of thecorrugated rollers have elongated bearings, which spindle-supportingframes are provided with vertical slots through parts fitted movably 011the frame of the machine, toothed racks on the spindle-supporting framesalongside the vertical slots, and bolts passing through the frame andthrough the vertical slots, which bolts are provided With nuts turningthereon and with toothed blocks adapted to engage the racks on theadjustable frames, substantially as and for the purpose set forth. 1

In testimony whereof I affix my signature in 5 5 presence of twoWitnesses.
